Question

how much current does an electric current seated row from to 20 volt line if the resistance of heater is 50 ohms

Answer 1

V=20volt
R=50 ohm
I=?

V=IR
I = V/R
I = 20/ 50
I = 0.4A
hope you understand....

Answer 2

Heya!!!!

here's your answer friend,

According to the ohm's law,

V = IR

therefore I = V/R

here V = 20v
and R = 50 ohms

therefore I = 20/50
I = 0.4 ampere is the current

Hope it helps you : )
